Audit of caesarean deliveries in a tertiary care hospital of northern Andhra Pradesh using modified Robson criteria

Background: Today, there is an increased trend in the incidence of caesarean section (CS) rate worldwide particularly in India, even with the lack of evidence supporting considerable maternal and perinatal benefits with higher CS rates. The main objective of our study was to find the incidence of CS rate, auditing the data on the basis of modified Robson criteria, factors responsible for the most common group, to know the changing trends of CS and finally put forth the strategies to reduce CS rate.Methods: This is a retrospective study of 472 CS cases carried out in a tertiary care hospital during the year 2016. All the cases were grouped according to the modified Robson criteria and the data was analyzed. The data were grouped into 3 different slots of 4 months each (FF = first four months; MF = middle four months and LF = last four months of the year 2016).Results: A significant increasing trend was observed in the groups of 2B and 5C where as a significant decreasing trend was noticed in 6C and 7C. The most common indications for caesarean delivery were cephalo-pelvic disproportion (CPD) (28%) and fetal distress (22%) in group 1 whereas in group 2A CPD, fetal distress and failed induction were found to be 12%, 24% and 30% respectively.Conclusions: The change in trend has been noticed in the last few months particularly in 2B and 5C groups suggesting that there is a change in the attitude of obstetricians in conducting caesarean deliveries before the onset of labour rather than performing CS after the onset of labour. Targeting 2B along with 5C would help our efforts in reducing the CS rate

Influence of different carbon sources on in vitro induction of anthocyanin pigments in callus cultures of petunia (Petunia hybrida)

Anthocyanins are naturally occurring compounds that impart color to fruits, flowers, vegetables, and plants. They are probably the most important group of visible plant pigments besides chlorophyll pigments. Apart from imparting color to plants, anthocyanins also have an array of health-promoting benefits, as they can protect against a variety of free radicals through a various number of mechanisms. Development of an efficient tissue culture system for commercial production of anthocyanins requires an integrated approach through manipulation of various media constituents. The effect of varied concentrations of different carbon sources on anthocyanin production in callus cultures of Petunia hybrida cv Bravo Blue was studied. Explants from young leaves were cultured on Murashige and Skoog (MS) medium supplemented with MS + IBA (19.6 µM) + Kin. (4.65 µM) + AdS (81.45 mM), 3% sucrose and 0.7% agar. Among the various carbon sources tested, incorporation of Glucose at 5% was found to have earliest pigment induction with maximum response coefficient with highest pigment content (1.36 ± 0.012 CV/g FCW). Highest gain in fresh cell weight was noticed with the addition of sucrose 5% (3.96 ± 0.06 g). When MS medium was supplemented with different concentrations of Galactose, the explants failed to respond

Genetic transformation of pigeonpea with rice chitinase gene

With a long-term plan to develop transgenic pigeonpea with resistance to fungal disease, the transfer of a rice chitinase gene to pigeonpea[Cajanus cajan (L.) Millsp.] is reported here. The rice chitinase gene harboured in the plasmid pCAMBIA 1302:RChit was delivered via the Agrobacterium-mediated method to the cotyledonary node explants followed by subsequent regeneration of complete plants on selection media containing hygromycin. Putative transformed pigeonpea plants were recovered with stringent selection pressure and confirmed using molecular techniques. Stable integration and expression of the chitinase gene has been confirmed in the T0 and T1 transgenics through molecular analysis

Performance and Stability of Pearl Millet Varieties for Grain Yield and Micronutrients in Arid and Semi-Arid Regions of India

Pearl millet [Pennisetum glaucum (L.) R. Br.] is grown under both arid and semi-arid conditions in India, where other cereals are hard to grow. Pearl millet cultivars, hybrids, and OPVs (open pollinated varieties) are tested and released by the All India Coordinated Research Project on Pearl Millet (AICRP-PM) across three zones (A1, A, and B) that are classified based on rainfall pattern. Except in locations with extreme weather conditions, hybrids dominate pearl millet growing areas, which can be attributed to hybrid vigor and the active role of the private sector. The importance of OPVs cannot be ruled out, owing to wider adaptation, lower input cost, and timely seed availability to subsidiary farmers cultivating this crop. This study was conducted to scrutinize the presently used test locations for evaluation of pearl millet OPVs across India, identify the best OPVs across locations, and determine the variation in grain Fe and Zn contents across locations in these regions. Six varieties were evaluated across 20 locations in A1 and A (pooled as A) and B zones along with three common checks and additional three zonal adapted checks in the respective zones during the 2019 rainy season. Recorded data on yield and quality traits were analyzed using genotype main effects and genotype × environment interaction biplot method. The genotype × environment (G × E) interaction was found to be highly significant for all the grain yield and agronomic traits and for both micronutrients (iron and zinc). However, genotypic effect (G) was four (productive tillers) to 49 (grain Fe content) times that of G × E interaction effect for various traits across zones that show the flexibility of OPVs. Ananthapuramu is the ideal test site for selecting pearl millet cultivars effectively for adaptation across India, while Ananthapuramu, Perumallapalle, and Gurugram can also be used as initial testing locations. OPVs MP 599 and MP 600 are identified as ideal genotypes, because they showed higher grain and fodder yields and stability compared with other cultivars. Iron and zinc concentration showed highly significant positive correlation (across environment = 0.83; p < 0.01), indicating possibility of simultaneous effective selection for both traits. Three common checks were found to be significantly low yielders than the test entries or zonal checks in individual zones and across India, indicating the potential of genetic improvement through OPVs

Conventional and Molecular Breeding Approaches for Biofortification of Pearl Millet

Pearl millet [Pennisetum glaucum (L.) R. Br.] is an essential diet of more than 90 million people in the semi-arid tropics of the world where droughts and low fertility of soils cause frequent failures of other crops. It is an important nutri-rich grain cereal in the drier regions of the world grown on 26 mha by millions of farmers (IFAD 1999; Yadav and Rai 2013). This makes pearl millet the sixth most important crop in the world and fourth most important food crop of the India, next to rice, wheat, and maize with annual cultivation over an area of ~8 mha. Pearl millet is also primary food crop in sub-Saharan Africa and is grown on 15 mha (Yadav and Rai 2013). The significant increase in productivity of pearl millet in India is attributed to development and adoption of hybrids of early to medium duration maturity. More than 120 diverse hybrids/varieties have been released till date for various production environments. The heterosis breeding and improved crop management technologies increased productivity substantially achieving higher increased production of 9.80 mt in 2016–2017 from 2.60 mt in 1950–1951 in spite of declined of area under the crop by 20–30% over last two decades (Yadav et al. 2012)

Mechanical and microstructural characterization of YSZ/Al2O3/CeO2 plasma sprayed coatings

In the present work, the surface characterization of YSZ/Al2O3/CeO2 plasma sprayed coatings was performed to understand the surface characteristics. The content of the Yttria-stabilized zirconia (YSZ) was 60 wt.% , where alumina was varied from 30 to 38 wt.% and CeO2 from 2 to 10 wt.%, respectively. Ceramic coatings with a different variation of composite materials were used to increase layer strength on a substrate of SS-304. The SEM micrographs were analysed to understand the features present on the surface of coatings, and XRD analysis was done to ascertain the phases present in the coatings. Micro­hardness and porosity decrease with the addition of CeO2 in the YSZ-based coatings
